Herbivorous silkworms, also known as ground silkworms, nectar, Baota vegetables and snail vegetables, are commonly known as ground cows in Chongqing. It is an annual or perennial herb, which can form underground tubers in Stachys of Labiatae. Originated in the north of China, it was cultivated and utilized as early as17th century, and now it is cultivated all over the country. Yangzhou, Jiangsu Province is widely planted, and its sauce processing of Yangzhou snail dishes is also very famous. The edible part of Stachys sieboldii is underground tuber, which is mostly used for processing and eating. After salting or pickling, it has a unique flavor, crispy and delicious, and is the top grade of kimchi and pickles. Qianjiang County, Chongqing is the main production base of Stachys sieboldii. At present, the cultivation area has reached 1500 mu. In recent years, Zhu Jing Shanzhen, a deep-processed product, has been developed with fresh Cordyceps sinensis as raw material through a certain technological process, which is favored by consumers. The industrialized development and utilization of green food in Zhu Jing has initially taken shape, which is becoming a new way for local farmers to get rid of poverty and become rich. ?

1, biometric?

The roots of Stachys sieboldii are shallow, the root length is only 10 cm, the aboveground part is upright, and the part touching the ground grows adventitious roots. The aboveground stems are square and quadrangular, with inverted bristles and side branches close to the ground. Stolon occurs in the underground part, and the top expands into a tuber, which is like a silkworm chrysalis. Leaves opposite, ovate or oblong-ovate, leaf margin obtuse-serrate, petiole short or petiole-free. The spike is attached to the top of the main stem and upper lateral branches. Flowers sessile or short-stalked, corolla white or lavender, calyx bell-shaped. Nutlets, black, oval or rectangular, contain a seed. ?

Herbivorous silkworm is a short-day plant, which likes humidity and is not resistant to high temperature and drought. Underground stems begin to germinate when the ground temperature is 8℃ in spring, and plants grow most vigorously at 20-25℃. After September in autumn, the growth on the ground slowed down, and several nodes at the top of the stolon began to swell and form tubers. After the winter, the above-ground part of first frost died and overwinters with underground stems. ?
